The invention discloses a pellet type
pantoprazole sodium enteric
capsule and a preparation method thereof. The pellet type
pantoprazole sodium enteric
capsule is a sustained-release preparation composed of a
capsule shell and uniformly mixed
pantoprazole sodium pellets held in the capsule shell; the
pantoprazole sodium pellet from inside to outside in turn comprises a blank pellet core, a main
drug layer, an
isolation layer and an enteric layer, wherein the weight of the main
drug layer is 14-55% of that of the blank pellet core, the weight of the
isolation layer is 9-10% of that of the total weight of the blank pellet core and the main
drug layer, the weight of the enteric layer is 28-32% of that of the total weight of the blank pellet core, the main drug layer and the
isolation layer; 40-60% of that of the
pantoprazole sodium pellet is coated with a pigmented layer on the outside of the enteric layer; the weight of the pigmented layer is 0.5-1% of that of the total weight of the blank pellet core, the main drug layer, the isolation layer and the enteric layer; the
diameter of the blank pellet core is 0.8-1.0 mm; the
granularity of the
pantoprazole sodium pellet is 14-20 mesh; each capsule contains 20-40 mg of the pantoprazole sodium. The pellet type pantoprazole sodium enteric capsule has the advantages of acidproof, rapid release and stable.
